sympy.transforms.inverse_mellin_transform() in python

With the help of inverse_mellin_transform method, we can compute the inverse mellin transform and return the function.

Syntax : inverse_mellin_transform(F, s, x, strip)
Return : Return the function F(x).

Example #1 :
In this example we can see that by using inverse_mellin_transform() method, we are able to get the function F(x) by performing inverse mallin transformation.

# import inverse_mellin_transform
from sympy.integrals.transforms import inverse_mellin_transform
from sympy import oo, gamma
from sympy.abc import x, s

# Using inverse_mellin_transform() method
gfg = inverse_mellin_transform(gamma(s), s, x, (0, oo))

print(gfg)

Output :

exp(-x)

Example #2 :

# import inverse_mellin_transform
from sympy.integrals.transforms import inverse_mellin_transform
from sympy import oo, gamma
from sympy.abc import x, s

# Using inverse_mellin_transform() method
gfg = inverse_mellin_transform(gamma(s + 1), s, x, (0, oo))

print(gfg)

Output :

x*exp(-x)
